The Adalet Wireless multi-point systems utilize the hazardous area, NEMA or DIN rail transmitters (in any combination) and a receiver configured for base unit mode. The base unit can communicate with up to 60 transmitters. Output from the base unit is communicated with Modbus. Local outputs with 3 alarms, one discrete and one analog output are also standard on the base units. The factory can configure the complete system you for quick installation. An interface program for system configuration is also available.

Each multipoint transmitter can accept several process variable inputs including 4 to 20mA, voltage, thermocouples, and RTDs as well as discrete on/off (switch) inputs. RTDs and thermocouples are linearized to temperature. The transmitter is available with three power options: 1) 120/240 Vac 2) +24 Vdc 3) battery power. The battery powered device utilizes two long-life rugged lithium batteries (up to four batteries in the explosion proof version). Battery life can be for several years under certain conditions. These devices utilize proven-reliable 900 MHz frequency hopping spread spectrum technology (FHSS). The output power can be adjusted to 1 watt, the maximum allowable by the FCC, to ensure data reception while achieving maximum transmission distance (miles in the case of line-of-site).
